Abstract

In this paper, we propose a demosaicking method that
uses a correlation between the wavelet subband
coefficients in the high frequency region of color channels
(R, G and B). In this paper, we introduce the pre-existing
demosaicking methods, and show that our proposed
method yields an outstanding performance through in
imitation tests compared to pre-existing methods in terms
of objective performance and subjective resolution.
